So the stock speakers suck. My subs added some nice lows, but then I wasn't hearing the highs.....so I decided to add some tweeters.

First thing I did was buy the Advanced Audio System sail panels (~$20-25 for the pair) that have tweeters in them from the factory with that option. I didn't order the stock tweeters with them though...just the panels.



Part Numbers:
Left - 22725265
Right - 22725264

For the tweeters, I used a set of Infinity Reference 1" silk dome (1011t) tweeters that I already had.



I went with flush mounting the tweeters in the panels to keep a smooth look. This his how they the Infinity's are set up....they have a threaded outside & a big plastic nut to hold it from behind.






First thing to do was drill out the mesh looking grille on the AAS panels. That was done with a 1 3/4" hole saw.



Then I took a Dremel to the leftover lip and tried to bevel down as much of the leftover "mesh" as possible.

Slide the tweeter thru the hole.



Then tighten down the big "nut" that screws onto the threaded tweeter assembly. Then tightened that down as much as possible.








Next was to run the crossover to the door speaker wiring. The Infinity's use inline crossovers.

Take the door panel off. Pop off the sail panel. Undo 2 screws in the door pull (under the rubber). Undo one screw in the front bottom corner. Then the door is held on by a bunch (6 or 7) of plastic clips--pry around the door or pull out towards you. Unplug the electrical harnesses before removing the door panel.



For the crossover wiring.....I just used 3M line taps on the speaker wiring--I know some people frown upon those, but they have always done the job for me & I'll take them out when I turn the car in and take the tweeters out.

As for the wire colors.....I don't know if these are right or not because I "thought" I wrote down the colors when I did the install, but I forgot to. Taking the door panel off was a pain in the ass, so I'm not gonna check now. But after searching thru wire diagrams it goes something like this:

Left Front:
+ Tan
- Grey

Right Front:
+ Dark Green
- Light Green

Run the crossover up to the door & the wires to the top by where the sail panel goes. I zip tied the extra wire to the stock wiring.



Put the door panel back on. Then the wiring should be exposed like this for the tweeters:



Plug the tweeter connections (came like this from Infinity already with the spade connectors) into the wiring & snap the panels back in. That's it!

The Infinity tweeters match the silver accents in the Ion perfectly too! They sound awesome & have really balanced the stereo out now
